I was afraid of that answer because I think one can forget it asking (or 
do you have some good contacts to Microsoft?).

I found:
1.) Disabling SMB2 (but not SMB1)
2.) Here's how SMB is used when related to SMB versions: When a Windows 
Server 2008/Vista "client" connects to a Windows 2000/XP/2003 "server", 
SMB 1.0 is used. Maybe \\server\share indicates/implies "old" 2000/XP/2003
